BUILDING WALL 2 Sheets-Sheet Filed May 11. 1927 abtonwq Patented June 17, 1930 LEN A. BANTA, OF CLEARFIELD, PENNSYLVANIA BUILDING WALL Application filed May 11, 1827. Serial No. 190,606.

' This invention relates to an improvement in bullding walls.

The object of the invention is to provide an improvedinsulating wall which may be used 5 in buildings or wherever desired and of a construction such that it will be a good insulator for heat, cold or sound, and is particularly adapted for refrigerators, refrigerator cars, etc, or wherever it is desired to proi vide an insulating wall or partition either for a building or an article of manufacture.

The invention relates to the formation of wall of a series of dead-air spaces which are made air-tight by means of liquid or plasi tic cement, covering the entire inner surfaces of the dead-air spaces. The wall is formed in a section by constructing a series of cells inclosing the sides thereof by means of a sheet or board, after which apredetermined quantity of plastic or liquid cement is poured into each of the cells and they are covered over by another sheet, upon which is built and likewise filled any number of additional cells to provide a wall of the desired thickness. It

'- may be of one cell thickness or any number as desired. After the section is thus closed and formed with the top board or sheet se cured over the cells, the entire section is mounted upon a shaft and rotated slowly in 0 order to allow the cement to run into and fill 0 dead-air spaces is preferably water-proof and air-proof, making the construction comparatively inexpensive and practical as well as forming an efficient andwell insulated wall that is waterproof and air-proof.

In the accompanying drawings:

Fig. 1 is aside elevation of a section of wall made in accordance with this invention 7 and mounted on the rotating shaft;

Fig. 2 is a disassembled View of the section of wall;

Fig. 3 is a transverse section through a portion of the Wall; and

Fig. i is an interior perspective View of a portion of one of the cells.

Thewallis preferably formed or constructed as shown more particularly in Fig. 2, in

'which one side 1 of the wall is placed in a flat position and upon this is secured the framework 2, which maybe formed of longitudinal and transverse members suitably crossed at intervals in order to reinforce the wall as well as to form cells 3. A suitable quantity of liquid or plastic cement is then poured into each of the cells 3 and another board or sheet 4 is secured over the tops of the cells entirely closing them." This provides a wall of one air space or cell thickness and may be used if desired, although the wall may be of two or more cells thickness, the one shown in the drawings being of two cells thickness. In this form, another frame 5 is secured upon the board or sheet 4 in order to form additional cells 6 therein, and these cells are likewise closed by a similar sheet or board 7, after they have received the desired or predetermined quantity of plastic cement. The sheet 7 forms one side of the wall while the sheet 1 forms the other.

As thus constructed, the section of the wall is then secured in suitable clamps 8 of any desired construction and mounted on a shaft or shafts 9, journaled in suitable bearings 10.

The construction and mounting of the clamps 8, shafts 9 and bearings 10 may be of any desired form, and theone shown in Fig. 1 is the wall is slowly rotated allowing the plastic or liqui dcement to run over all of theinternal surfaces of the cells Sand 6, filling the cracks and crevices and truly forming closed deadair spaces or cellswithin the; wall. Attention is called to'Fig. 4 as showing the manner in which theplas'tic cement. fills the cracks and covers the surfaces of the cells;

After removal fromthe clamps 8, the section ofwallmay be fitted into place wherever it isdesired to be used The wall may be built of any desired size and shape, according to its use, and it is not desired to limit theinvention to the exact form shown.

The building wall thus formed provides a water-proof and air-proof structure and is a d insulator for heat, cold or sound, this ing accomplished by the closed, dead-air spaces of w ich the wall is formed. The wall is articularly adaptable for refrigerators, re rigerator cars, and suitable structure, or wherever it is desired to vide an insulating wall or partition for a buildin or an article of manufacture. The wall as t us formed is inexpensive and thoroughly practical. The cost of such a wall would be about fifteen cents er square foot as compared with sixty (60 per square foot, for the ordinary refrigerator wall, and is more eflicient because it is .a better insulator than is usually thus the ordinary refrigerator wall. a

The wall ma be constructed of any suitable material desired, as for instance wood or a co 'te material, or whatever it may be foun advanta cons to use. The use of the word cement in the claims is intended to oovernot only all forms of cements but also glues and other plastic or liquid sub stances which may be used for coating the interior of theair spaces or cells to render these substantially air-tight.
